NAME

XML::LibXML::RegExp - XML::LibXML::RegExp - interface to libxml2 regular expressions

SYNOPSIS

   use XML::LibXML;
   my $compiled_re = new XML::LibXML::RegExp('[0-9]{5}(-[0-9]{4})?');
   if ($compiled_re->isDeterministic()) { ... }
   if ($compiled_re->matches($string)) { ... }
 
   $compiled_re = XML::LibXML::RegExp->new( $regexp_str );
   $bool = $compiled_re->matches($string);
   $bool = $compiled_re->isDeterministic();
 
 

DESCRIPTION

This is a perl interface to libxml2's implementation of regular expressions, which are used e.g. for validation of XML Schema simple types (pattern facet).

new()

   $compiled_re = XML::LibXML::RegExp->new( $regexp_str );
 
 

The constructor takes a string containing a regular expression and returns a compiled regexp object.

matches($string)

   $bool = $compiled_re->matches($string);
 
 

Given a string value, returns a true value if the value is matched by the compiled regular expression.

isDeterministic()

   $bool = $compiled_re->isDeterministic();
 
 

Returns a true value if the regular expression is deterministic; returns false otherwise. (See the definition of determinism in the XML spec (http://www.w3.org/TR/REC-xml/#determinism <http://www.w3.org/TR/REC-xml/#determinism>))
